Bimanual Rhythmic Coordination in Children: A Dynamical Approach
Pages 4

Timing in a bimanual rhythmic tapping task in children of different ages is studied from a dynamical approach of movement coordination. According to this approach, interlirnb timing is an emergent property of the intrinsic dynamics of the system. These dynamics are determined by the interaction between organismic, environmental and task constraints that act on it (Newell, 1985). During development, the intrinsic dynamics are adapted to changes in these constraints. This adaptation or tuning modifies the region in parameter space in which coordination patterns are stable. Hence, by studying the stability and instability of coordination patterns, developmental changes in the intrinsic dynamics can be described.
